Dynamics CRM on Linux (Possibly Mac)

We were recently contacted by a client with a pretty difficult requirement: They had to be able to use CRM on Linux desktops. We have been searching for a solution that addresses accessing CRM via a mac for a while now but haven't had much of a call for using it on Linux workstations. There are a few solutions we've seen that relate to using VMware (such as in Matt Whittemann's post here) or running it in a virtual environment such as parallels.

While researching this problem I happened to stumble across IEs4Linux. It's an installer that grabs the proper windows cabs, installs and then configures IE6(or 4/5) in a bottled wine instance. After some testing we concluded that it would provide a fairly stable environment for CRM on Linux. The screenshots below show CRM running in IE6 on a gnome desktop.

Performance was ok on an aging Celeron with 512mb's of memory. I would recommend something a little beefier for better performance. Keep in mind that this doesn't include the Microsoft Outlook client addin so still no way to integrate mail other than using the e-mail router and exchange rules to dump it in directly.
