About 15 of the accounts will be for combined self-service and workstation access, the rest for workstation use only.

Note for linux users: the University normally has packet filters in place which mean that once you get an IP address you still won't be able to get anywhere (they assume you are using Windows and subsequently connect to an RAS server). However, these filters should be removed for the duration of the IoP meeting.
