That would be quite a bit of work, but it is technically possible to
run i386/PPC/x86-64 cross-compiled executables with qemu _without_ a
VM. See the following example from my i386 box:
$ uname -a
Linux hsh 2.6.21-rc1-def01 #1 SMP PREEMPT Wed Feb 21 09:28:23 CET 2007
i686 Intel(R) Pentium(R) M processor 1.73GHz GenuineIntel GNU/Linux
$ file /opt/eldk/ppc-linux/lib/ld.so.1
/opt/eldk/ppc-linux/lib/ld.so.1: ELF 32-bit MSB shared object, PowerPC
or cisco 4500, version 1 (SYSV), not stripped
$ qemu-ppc /opt/eldk/ppc-linux/lib/ld.so.1
Usage: ld.so [OPTION]... EXECUTABLE-FILE [ARGS-FOR-PROGRAM...]

This doesn't solve the "specific conf" class of problems, neither the
different OS part.

Regarding a dedicated server, a virtual hosted server costs from 10€
to 30€ / month http://www.amen.fr/static/serveur_prive.html . Any
thoughts on corporate sponsoring?
