Other than Salesforce.com's AppExchange, are any business-oriented software marketplaces for add-ons getting traction?<p>I've looked into WebEx Connect Marketplace (vaporware?) and Google Solution Marketplace (anyone else heard of it?), but other than AppExchange I can't see anyone making much of a go of it (yet).<p>I expect that more AppExchange-like marketplaces to emerge to provide a more cohesive experience as Enterprise shifts out from corporate hardware to cloud/Saas-based platforms, but am not seeing much action just yet.<p>Has anyone got a clear fix on emerging contenders?
My impression is that they are all platform dependent. I know that people are selling QuickBooks apps, but I dont know if there is any marketplace for them. Maybe something sponsored by QuickBooks. In the 90's there was a lot of hype about components, but I dont think it got a lot of traction.
