That depends. WiX isn't really easy to handle.

But you can't update all libs. Subversion just doesn't compile/link with
all the newest lib versions. For example, the latest neon version can
only be linked with Subversion trunk, not the 1.2.x branch.

Well, apart from wrong assumptions (I don't have a desktop computer to
reuse HDD's, CD/DVD, AC-Unit, tower, sound/graphic card - I only have a
laptop computer due to not enough space in my apartment), your
calculations are correct. But only 512MB RAM for an x64? Whenever I read
something about XP64 and what the recommended system is for it, they all
tell to use at least double the RAM of the same system using 'normal'
XP. Don't forget, I'd have to install VS.NET there too to be able to
debug possible problems.

Thanks a lot for the offer. But I don't think I'd be comfortable to take
money from you to buy an x86 system. That entry in the FAQ was more
meant as a joke. Of course, if a company selling x86 chips or computers
would like to provide such a system, I wouln't say no. After all, that
would be 'marketing' for them.

Since TSVN is an open source project, I'd rather have someone else who
already *has* such a system support the x86 port of TSVN.
