@ Kermode: Portable
freeware site; "Portable
Payware Discussion" subforum.
One of the (many) things I appreciate about this site is that there is space provided in the forums to mention/discuss applications that have one or more "strikes" disqualifying them from inclusion in the overall database--be that "payware" status, JAVA or .NET dependencies, etc. Sure, Reaper's not getting added to the TPFC database proper anytime soon, but I was glad to find out about it here from portackager's original post, and I was just giving my opinion as a now-user on the program he pointed out. It's not like either of us are spammers for it. (I know I'm relatively new here, but I'd like to think that ~65 posts count for
something.

)
But since this thread's been resurrected, a program update: Reaper is up to ver. 3.05, and they've
significantly relaxed the licensing restrictions for the discount license. The cheaper license of the two (now $60) is valid "if any of the following is true:
1. You are an individual, using REAPER only for personal use.
2. You are an individual or business, using REAPER for commercial use, and the yearly gross revenue does not exceed USD $20,000.
3. You are an educational or non-profit organization."
The second and third points are new--since version 3.0, I believe.
Oh, and even the OS X version can be used portably (instructions
here).
