Looking at the bytecoin block explorer:

14274 2013-04-09 08:43:05
14273 2013-04-09 08:29:06
14272 2013-04-09 07:36:09
14271 2013-04-09 07:25:46
14270 2013-04-09 06:16:47
14269 2013-04-09 05:14:39
Those timestamps don't look good.
I've gotten a transaction from block 14276 (or later), but the block explorer doesn't appear to have picked it up, yet.
It looks like altcoin users are going to have to plan on providing the bulk of hashing power for their own networks. If your chain is wildly profitable, it's a sign that your chain is vulnerable to being left high and dry when massive amounts of hashing power enter and then depart your network.
Thumbs up for thumbs up guy, and here's hoping that more hashing power ensures the continued viability of these networks.
