What about email? If you use exchange you could wipe through exchange, other wise IPCU could do it. MDM is overboard for your situation. Do these have 3G data plans and access? Are users going to have itunes on their office pc's to synch with these? You should set up an account with the Business VPP store so you have control over what is purchased and not have to gift or do reimbursement. The end user would get the redeem code.
I completely forgot about IPCU. We use Exchange for office email, but our IT guy doesn't like to 'experiment with new features,' hence why we're running 2003.
We've only got wifi on these and the boss would rather not have iTunes on the workstations. Today I've been testing iAnnotate and PDF Expert through my Dropbox account before I go through the process of trying to convince IT to enable webDAV on our server.
I only see us using 4-6 "work" apps, but I'll check with the boss to see if he setup his account on the VPP when he ordered these.

The name is rather unfortunate in your situation. iTunes came out as a way buying music for the iPad. Apple had iTunes around, so they added features over time. It's now a device manager for all Apple i devices. It's more than a way to purchase music.
Do you take the iPad on customer visits. iTunes can load presentation on iPad.
If you sync the iPad on multiple computers, check this out.
ps. Windows makes you paranoid.
If it is not broke, do not fix it.
