Thanks y'all. I definitely need file transfer and our use case is not necessarily for 1 to 1 but 1 to many, i.e. I would need to be able to connect to lots of laptop/pc's that don't belong to me. Essentially, I support the programmers in the field and need to connect to their machines, which I likely would never have credentials for. It seems like most software models in this arena are more geared towards connecting to your own devices. At surface level, from what I can tell splashtop is the only one that fits the bill so I'll give that a go.
