samk and wavedreamer, regarding XenClient, TxT and TPMs...
I haven't been able to find the subject of TxT or TPM compatibility on any of the XenClient support forums, and I haven't heard back from a direct inquiry sent to Citrix, however I did hear from Wave that Citrix is still working on the TxT feature as planned. I just don't know how soon or whether it will be delayed until release of the next version. In any case, it's fairly inconceivable to me that Citrix and Intel would have spent so much time and money on integrating TxT with XenClient and then just drop it for no apparent reason. I wouldn't be overly alarmed at this point since it's not uncommon for new product releases to have issues beyond the beta stage.
