How many pts/hour does this make? For how many hours?

A $200 free credit isn't free. It's going to be worth $200 if it turns out you need a cloud computing for a server or something. So as not to lose money, evaluating your probability of needing cloud and expected time of that event is needed.

Either you send first, or escrow (you pay the fee).

I already made one successful trade (price rises though ) so you can trust me. I have many pts to sell.

Very fast, excellent, would recommend

I just compared md5sum of protoshares-qt.exe with one from http://the-iland.net/static/downloads/protoshares-0.2.0.zip and they're identical

Not that I know the guy, but stealing the first deposit would be the dumbest scam ever, especially when such market is really in demand. The page looks nice. 
Probably just a bug.

The cycle algorithm idea is wrong, there's no cycle in the 50 bit hash. The cycle is in 512 bit sha output, but that's equivalent to finding sha512 collisions.

Regardless of birthday algorithm, generating 2^23 sha512 on radeon 5870 (no oc) takes 180ms. 64 bit values and 1024 block makes parallelism on current compute units hard. That's close to output of new intel cpu. So gpus aren't going to win by a big margin, like with bitcoin's sha256. 
The collision finding time, even on a cpu, is almost insignificant, 2^26 is a small value. 
I'm writing gpu miner as an opencl learning experience. Looks like finding all birthdays in 2^26 hashes is going to take 200-400ms on radeon 5870.

edit: 70ms for sha512, so not that bad. (optimizing opencl is completely different from cpu, and I'm not talking about obvious sequential vs parallel differences), time for the harder part.
