Assuming people "interface -> face" their OS, then maybe.The one problem might be, though, wouldn't this conflict with the likely description of systems that use a graphical interface, like OTL's Windows? If no one minds the suggestion, perhaps I can offer "I need to browse my messages", and "I need to access/link to the server". Which may be a tad more convergent but makes a little more sense, IMHO(no offense meant, though).
DigiExpress could work pretty well, I suppose, though probably more as a service(much as the original Pony Express was itself a service) than the function itself, TBH. (think: America Online in the real world).
I was trying to think of quick abbreviated terms. Much like e-mail is short for electronic mail, but e-mail is much easier to say. I figure some computer scientist could liken TTL's *e-mail to a "Digital Pony Express" and then the term catches on, and is shortened over and over. DP Express?
