Need to evaluate client machines and network

[bopritchard]

I've got a web app that has set of specific requirements for my user's client machine (processor, RAM, etc...) and their network (upload/download speed)...

So I need a tool that will ideally allow my potential clients to go to a site that will launch an applet that will scan their system and network and log each of these items that I can then review...

I've been to Ookla Net Metrics which handles the network side of things but it doesn't report on the client machine.

Any help would be much appreciated...
