Oh, really. IrDA is more secure? How so? I've been able to open the garage of my neighbor using the remote control of my garage. There are devices to put off TVs of other people using a remote control. With BlueTooth, you can at least ut a password on it, and hide your device.

Besides that, one can easily use VPN over BlueTooth to establish a secure connection provided both endpoints support this. The endpoint doesn't have to be a phone. For example, you can use server (VPN) <-> 3G <-> mobile phone <-> BlueTooth <-> NIT (VPN). To transfer files, one could use e.g. GPG.

If your employer bans BT I think they don't want you to use IR either. Too bad. So you abide to the rule(s) by putting your BT chip (or device) off, put it in a Faraday, you use a different device without BT, you get a IrDA addon for your device, you put BT on invisible, or you find a smarter employer.
