I've seen a couple that don't handle HTML, at least not without some external
assistance. I'm also pretty sure there's one or two that handle in-band HTML,
but don't handle anything HTTP-ish. Not mainstream, but not one
guy and a dog either.

HTTP is worse than SMTP, though, as you'd either need to
implement yet another store-and-forward approach or disable the
TiS button unless there's a live internet connection.
