chroot or xen? + general questions

Hi

I am considering to switch from Arch to Alpine, but will still require some applications still not available in Alpine - most importantly
LibreOffice (in the ports? - is there a searchable web interface for what is available there like the AUR?) and citrix receiver (binary, so glibc dependent - I could possibly try to run the windows variant under Wine..., but that would mean also running a browser under Wine.... :( ).

I found this wiki page that would make life much easier
http://wiki.alpinelinux.org/wiki/ArchLinux_install_inside_an_Alpine_chroot
now that pacman is in the packages, I guess one could do the bootstrap without installing bash and wget... ?

and with some fiddling it might even be possible to get it nicely integrated in the rest of the system (something like schroot?)
https://wiki.archlinux.org/index.php/Schroot
especially the minimal 32-bit variant could be interesting.

An alternative would ofcourse be to do Xen and run applications like that - however: Can one configure Xen guests to directly access files on the home partition?
What would be the best solution? A QubesOS-like solution, but with Alpine as Dom0 could be cool...
