Any tips on Pervasive SQL Server?

My company is about to purchase an app that will have Pervasive SQL Server as its base. The client will be running on W98 desktops over a Novell 5.1 network with TCP/IP as the protocol. We figure anywhere from 100 to 200 users of the app.

We have never used Pervasive before. It has been a MS SQL shop up to now.

Are there any iregularities (shortcommings/glitches/oddities) that I should know of beforehand?

Thanks.
