Virgin/Google Mail in UK to block .Pages docs?

Virgin’s new plan to use Google Apps for email might have just hit a small snag for its Mac users.  According to their new FAQ, .pages  (iWork word processor) docs won’t be accepted as incoming email attachements, even when zipped.  I’ve personally sent Pages docs through my enterprise Google mail so this must be a communication issue between Virgin and Google…unless there are .pages viruses we aren’t familiar with?

We hope it gets cleared up before too long.  Anyone know someone at Virgin who can clarify this?  Thanks Rob!
