Working on dreamhost site offline



I have a long commute a couple of days a week with no wireless for large parts of it ( rural Ireland). I would like to be able to hack on some of my dreamhost projects during this commute. Currently i have a virtual box running turnkey for wordpress. I would like to try and replicate the config of wordpress , zencart and perhaps some others on my virtual machine, do the dev there and move it over to dreamhost when i am done.

Does any such virtual image exist , if not, does anybody have any suggestions ?
