Domain Question

I have had a look at loads of posts about joining multiple domains but my question is a little different.

I have an XP Pro Laptop provided by the company I work for; it?s used for Out of hours support.
I when in the office I connect to a Win 2K3 Domain. Obviously at the Logon I have the option to join the Domain or Logon Locally.

What I would like to know is, is it possible to have the company Domain, Local Logon and the Workgroup Domains listed at Logon?

I used to use my PC at home to provide Support and have some files on there I would like to transfer onto the Laptop. I could just Burn a CD with them all on, but I would still like the Laptop to connect to my Home Local Domain so I have access to accessories such as Printer.

Is it possible or is it the same problem as joining 2 Corporate Domains?

Thanks in advance
