• Split key address generation, ability to use with a bounty pool.
  Support for additive public keys has been implemented, which will be specified via a new command line argument.  Also present is a new miner program that works with ThePiachu's vanity pool.  This feature is available in the current github trunk, and will be in the next release.
  Thanks go to BurtW and others who made concise posts on this topic.
• Ability to generate P2SH (type-3) addresses
  Luke-jr contributed a patch to generate private keys that, when added to a single address multi-signature script, hash to a desired type-3 vanity address.  This is a very convenient way of doing it, because it works with the addmultisigaddress command in the unmodified Satoshi client.  This feature will be in the next release.
  As several folks have pointed out, by placing a nonce of some sort into the script, it is possible to generate type-3 addresses much more efficiently and without any elliptic curve operations.  However, getting a specific bitcoin client to support this is the main obstacle.
• Ability to generate compressed public keys
  Currently reading about this issue.
• How do I get oclvanitygen to use all of my GPUs?
  Support for using multiple GPUs from the same instance will not be very difficult to do, and is planned for a future release.
• Help, oclvanitygen doesn't work with Catalyst prior to 11.11
  This needs to go in the FAQ.  I believe this is the issue that Rassah reported a while back.  I added some OpenCL diagnostics, and Rassah sent me some traces, but I couldn't come up with a good explanation of what was going on, and would have had to ask for a lot of experimentation.  Since folks who have reported issues similar to Rassah's have also reported success with Catalyst 11.11, fully understanding and possibly fixing this isn't high priority.
• This program doesn't have a GUI / when I double-click on vanitygen, a window pops up and immediately disappears.
  Under consideration for the future, seeking ideas/code.
  The FAQ could certainly do a better job of explaining how to launch vanitygen.  Deepceleron, I really liked your earlier post, it has instructions that are very clear and concise.  If it's okay with you, I'd like to merge that into the FAQ.
• oclvanitygen runs really slow with the -r flag
  Currently oclvanitygen lets you search for regular expressions, but the regex matching is performed on the CPU.  There's no easy or gainful way to do regex matching on the GPU.  Having oclvanitygen accept regexes currently causes more confusion than it's worth, and it needs to be removed.  Don't expect it to be present in the next release.
• Ability to specify case-sensitive and case-insensitive prefixes at the same time
  This could be handled by supporting multiple -f options, with the case-sensitive file first, then -i, then the case-insensitive file.  Sound OK?
• The link to the file is broken
  Sendspace is not the best place to host this stuff.  Seeking alternatives.  It might also be desirable to sign future releases with a bitcoin address signature instead of GPG, but I'm not sure of the best way to do it that will be convenient to verify.

>vanitygen.exe
Vanitygen 0.17 (OpenSSL 1.0.0d 8 Feb 2011)
Usage: vanitygen.exe [-vqrikNT] [-t ] [-f |-] [...]
Generates a bitcoin receiving address matching , and outputs the
address and associated private key.  The private key may be stored in a safe
location or imported into a bitcoin client to spend any balance received on
the address.
By default,  is interpreted as an exact prefix.

Options:
-v            Verbose output
-q            Quiet output
-r            Use regular expression match instead of prefix
              (Feasibility of expression is not checked)
-i            Case-insensitive prefix search
-k            Keep pattern and continue search after finding a match
-N            Generate namecoin address
-T            Generate bitcoin testnet address
-X   Generate address with the given version
-t   Set number of worker threads (Default: number of CPUs)
-f      File containing list of patterns, one per line
              (Use "-" as the file name for stdin)
-o      Write pattern matches to 
-s      Seed random number generator from
