Thank you MichaelLax!
Indeed my process is the following at this moment:
- find the 'fossil file' to be retrieved on the Lion mac
- drag it to the desktop
- launch Virtualbox, which is set to connect to the Lion machine and show its (shared) desktop as an open folder there
- see the fossil file in the folder, launch it (say, Appleworks starts), retrieve data, potentially update and save (with the effect the original file is updated straight in Lion, not on a virtual disk)
- quit Virtualbox, put the fossil file back where it was.
My main worry (but it's just a worry) is, Virtualbox doesn't transfer clipboards between guest Snow Leopard and Lion host, and won't go up to the efficiency it shows for MS Windows integration (where you just have to double-click the win file inside host to automatically trigger all the rest).
Can you tell me if clipboards are transmitted in Parallels for a Lion host / Snow Leo guest pair?
As concerns the "better automation", I wonder whether a couple of scripts wouldn't solve it: for instance, in Lion, maybe
- I can trigger a script through a file association ("open all Appleworks files with... Virtualbox"),
- then this script starts Virtualbox and copies the original document to a shared folder,
- then inside Virtualbox's Snow Leopard another script is running and just waits for a file to appear in the same shared folder,
- this second SL script then launches the said file...
Somehow I stil have to handle the going back if the file is updated, but my present need really is just reading the file contents, and sometimes copying it.
I suspect the same strategy would work with Parallels.
Any scripting specialists welcome ;-)
