(P.S. sorry about my poor English, I'm from Russia)
First of all i'd like to thank your team for such a good product! We have a file server which have bottleneck in IOPS Perfomance of storage system. For a long time i've searched how to solve this problem, and I think your FancyCache can help very much.
At first I tested it on my work computer, and get next results:
My system have 3 volumes, C - system, D - work files (very fragmented with about 5% free space), Z - new and clean SSD OCZ Vertex-2 (took it for this tests).
I've used FuncyCache for Volumes.
Firstly i set up FC to cache Volume D and tested it for about 3 days very intensively without any problems. Results a very encouraging. I attached it to this post, you can use it on your site if you want. I've tested using AS SSD Benchmark and IOMeter, tests are for pure HDD, HDD+FC Lev.1 on RAM, pure SSD, HDD+FC Lev.1 on RAM and Lev.2 on SSD with different settings. Iometer tests are for 4k, 66% read - 33% write, 50% random - 50% seq.
After that i stoped caching vol.D and started it for vol.C to test for some days in working environment. And from that moment begin problems. After some time from starting FC (from 3 min to 1 hour) Windows hangs

At that time computer doesn't used very intensively, just web-browsing in Firefox or Opera, with many open pages, some with Flash content. I checked it about 5-8 times with R/W cache and Only Read Cache with same results. After than stopped FC and now working about 2 days without problems.
If I can help to deeper investigate this problem, I'd be happy to help, just tell what I should do. I don't think that there is any Dump because Windows can't get to BSOD...
Another questions:
1. When approximately you plan to release FancyCache (few months or maybe year or two...)?
2. What will be approx. price for x64 server?
3. How FC works with Microsoft Cluster Service? Now we have fileserver on MSCS of two Win'2003 servers...
