[gentoo-dev] cross compiling for a slow system

I have a laptop with a p2 running at 300mhz and 128mb ram.
While this is enough for ssh sesions to other hosts at work 
and browsing the web, or even playing a film with mplayer,  
everytime glibc gets updated I start looking out for alternatives 
to building glibc on the laptop. It simply takes too much time.

I run distcc to compile most packages on the laptop, and
together with the 3 other gentoo hosts on my lan compilation
times for most packages are acceptable. But glibc does not
build with distcc.

Is there an easy automated way to build huge packages such as 
glibc, xorg and mozilla as a tbz package on a fast system, using 
foreign C- and USEFLAGS, and then install the tbz's on the target host?

And if not, how easily do you reckon this could be implemented in
portage? I'm quite profficient in python, so I might give this a go 
in my free time if it did not require a near portage rewrite.

thanks
stefan
