CDJ/RB user, How can I play on someone else's DDJ/RB setup?

I have XDJ-1000m2's as well as CDJ-900's, w/ a DJM-800 mixer.  I use a flash drive to play (the decks are networked together).  I don't have the decks connected to my laptop at all.  When I play gigs, I normally just bring my flash drives.

Now I have some friends who have Pioneer controller setups with RB-DJ and I need to play on their setups with my music.  Is this possible?

Ideally my dream is that I can plug my flash drive exported from my RB and plug it into their laptop and have it come up the same as if I plugged it into a Pioneer CDJ/XDJ.. but I suspect that won't work.  It should tho!

But if there's no way to do that, is there any reasonable way to copy my RB database/audio fies onto an external hard disk and be able to plug that disk into their laptop and use that database and audio files instead of theirs.. temporarily?  Without messing up their own setup?

Or, if I can't do that, can I take a disk with my music files (no rekordbox data) and plug it into their laptop and play those tracks without importing them into their RB database and messing it up?

Basically, how do I step up to someone else's RB DJ controller setup and start DJing with my music from my XDJ/CDJ setup.. without messing up their setup?  That is what I need to do.

Thanks!
