Not possible with that they currently provide, but if they had an ARM version or the source code then it would take some effort (how much depends on the code) but still be possible.

I'm not sure what HP virtual room supplies, but if you're looking for an office package, things like Word processing etc, there's a version of Open Office that runs under Easy Debian, and some things like gnumeric, koffice, docstogo etc that you can get running on the n900.
