For the entire Infinitecoin network as a whole you can view the current difficulty on the uppermost (ie the most recent) block on the block explorer at
http://exploretheblocks.com:2750/chain/Infinitecoin . The "Block" number on that page will show you how many blocks have been found so far in total by the entire Infinitecoin network.
You can also view the current difficulty and number of blocks using your Infinitecoin wallet program on your pc. Start the Infinitecoin program, and wait for it to synchronise and download any blocks it needs to get itself up to date. Then from the top menu go to "Help", select "Debug Window" from the drop-down menu and the click the "Console" Tab. Then where you see the ">" sign at the bottom, type
getinfo
Press enter and you 'll see "difficulty" of the entire Infinitecoin network and "blocks" which is the total number of Infinitecoin blocks that have been found by the entire infinitecoin network until now. You'll also see some other information too.
If, at the ">" sign you enter
getmininginfo
You'll get some more interesting stuff including "networkhashps" which is the total hashes per second if the whole Infinitecoin network (divide by 1,000 to get Kh/s or by 1,000,000 to get Mh/s).
For the pool, the "Local rate" figure on the stats page at
http://treasurequarry.com:9844/static/ will give you the total pool hashrate.
The "Share difficulty" figure is still displaying incorrectly (I'm still waiting for a reply from the other thread about this). Currently it's showing a 0.56 according to the p2pool log (this seems to be wobbling much more than I'd expect but whatever it's doing it's the difficulty for all miners so everyone should be on an equally fair footing when it comes to finding shares). If there's not a fix to this difficulty oddness posted by tomorrow I'll roll back to the previous stable version of p2pool that we were using before this weekend until another upgrade comes along.
