What would be the best solution to running Lightroom on multiple computers? I already keep all my files stored on an external drive which is then duplicated on a RAID drive just in case any crashes. So I have three copies at all time. Now the catalogs and all the lightroom files are stored locally on the computer, if these files are moved to an external, I'm sure speeds would be affected greatly? Unless you have a really fast external. I'd like to hear your guys thoughts about running multiple set ups while staying seamless without having to constantly update one catalog.
