P6 Professional, not EPPM which is a different can of worms.
.1. on your system - if you have a serial number, can't you just keep paying the "maint. fee" and then keep getting updates for free - isn't this the best way to go?
.2. through citrix or similar - is this the above but through a corp VPM?
.3. set up on a network, at a corporation, can login to it remotely somehow I think.
similar but different:
.1. cloud access - called P6, but does not have all the abilities, ie cannot import layouts etc. - might provide a regular P6 access somehow.
What am I missing.
