I just started using another site that allows you to install multiple applications at once, similar to http://ninite.com/. This one is called AllMyApps.
The main differences between Ninite and AllMyApps is that AllMyApps lets you install only 4 or 5 applications without registering and it has a much broader selection of applications to install than Ninite.
For instance, Ninite doesn't install LogMeIn, so I always have to install that separately. But not with AllMyApps.
I haven't tested the AllMyApps installer process yet, so I can't vouch for it at this time.
