What I'm planning to do is not exactly a secret but I want to unveil it 
properly once it's ready for a beta stage. I've got an unstable base at 
the moment. If you have lots of time and you're really curious, I have 
posted about the idea on TLUG before. :)

I'd love the dedicated machines. At the moment it might not be feasible 
for me given my budget, but it might be a good way to release the thing 
initially. Once (if) it gets popular, I will find or collect the money 
to push it to a proper setup.

How much? Give me a link to the site.

Luckily memory won't be much of an issue. I'm so strapped for cash right 
now (thanks to everyone who's sending me emails about hosting) that it 
has to be the deciding factor. If once my "product" goes beta and gets 
popular and /actually needs the better hardware/, I will consider going 
to a more expensive solution and will, of course, encourage the 
companies that TLUGgers work for or recommend before any others.
