Actually making this a Citrix or similar client would be a good move - I was reading only the other day about the problem of Windows PCs that are only used as Citrix clients which get infected with viruses that could grab corporate passwords.
I think having a really low cost locked-down Citrix client that can also run web apps directly would be quite attractive to corporates, particularly if it can also be configured to only connect via corporate VPN (which avoids the insecurity of open public WiFi).
