I do this a fair bit, and my code is big enough to make compilation a
practical necessity. I use the mzc && mzscheme solution.

However, there are still some oddities. I have loads of dev links to
PLaneT packages, and those have to be recompiled too.

Sometimes (not sure what the trigger for this is) mzc doesn't follow the
dependencies properly and I have to some bytecode nuking to get things

This is something I'd be very much in favour of. I think it would fix  
all of
the above problems.
