My advice is for you to to consolidate your work into one wireless laptop.
I just yesterday deactivated/uninstalled the Sony Library from my work computer for a couple of reasons. (e.g. separation of church and state
).
I try to keep my personal stuff off the work computer(s), but if your work involves using your reader etc. then I'm sure it's appropriate.
I do believe calibre has some network-type version, but I don't know that would be accessable from "anywhere."
I run my main Calibre install on my home desktop but have a backup/copy of it on my netbook as well and in addition keep (and backup) an ebook directory which I throw everything into.
Enjoy!
