It doesn't.

Assuming my math isn't terrible, this is 1.4GB/hr.

I'd like to point out that many systems use 32bit processes in which case the entire usable application address space is 2gb (that includes the app and its overhead).

Your UA+Libraries+application are probably going to consume ~100mb, on top of the first hour of recording (1hr * 1.4GB/hr), which means that there's probably another .5GB available, rounding that gives you perhaps another 20minutes [1hr * (1/(1.4 [GB/hr] / .5 [GB] ~= 1.5/.5) ~= 1/3)].

That means you have 80minutes, which is unfortunate if you're trying to deal with a 90 minute conference call (which conveniently is the length of the MC TF calls).

Note that actually running a web browser in 64bit world tends to cause it to waste more memory (because the pointer size generally doubles, and browsers use *lots* of pointers), so even if a mobile device could use 64 bit memory blobs, the UA wouldn't want to (it's better off using multiple processes).

I'm sorry for the delay, I've been worrying about other things.
