Hi Pete,

  unfortunately I play tennis from 19-20 on Tuesday's.

The main issues I've at the moment are:

- build procedure of sec modules separate from xrootd.
  Currently we can build xrootd and therefore the sec modules only
  on Linux and Solaris, however we really require the netx client to be
  able to build on all ROOT supported platforms, incl Win32. Since for
  the time being the building of the client is linked to the building
  of the server we have the client only on Linux and Solaris.
- support for "localhost" in the url (backward compatible with TNetFile)

Cheers, Fons.
