As I mentioned in my first article, the "commercial offering" that I had access to was Teamviewer. I have used both Logmein and ShowmyPC as well, but in a much more limited fashion. (I.E. I use Teamviewer every single day for my day job, the other two only very occasionally.)
In truth though, I recognise that both of these offerings haven't been properly reviewed, and i am considering doing a set of articles comparing the various commercial remote offerings to each other. Do you have specific "killer features" in either of these products that you admire? Something that makes them stand out from Teamviewer, (or each other?) Or are they, (as my initial impression of them was, based on my admittedly brief exposure to them,) about on par with Teamviewer?
