Is anyone on the DNN Forums a member of StomperNet, the SEO / eCommerce training organization based in Atlanta Georgia?

I am a member of StomperNet and the SN membership portal uses DNN for its members. But I don't know of anyone that uses DNN for large eCommerce sites that is in SN. The SN crew typically sticks with YahooStores, FinestShops, Volusion, OSCommerce, custom xCart, etc. 

I am just curious if anyone thinks or has proven that you can achieve similar SEO /eComm results using DNN and one of the eComm modules....probably ASPDotNetStorefront. There always seems to be talk of URL issues on some dynamic systems that causes issues, etc. Obviously I am not an SEO guru yet and not sure of all the reasons why some think that DNN is not that great from an SEO perspective. Maybe some gurus could talk about DNN and any limitations it might have from and SEO perspective, or how these limitations have been addressed in recent updates. I am aware of the limitations for the SolPart menu being spidered since it uses javascript, but there are other menu options. And in some cases it might be nice to use SolPart for some site menu structure that you would typically not want to have spidered anyway, such as About Us, Shipping Policies, and the like. Then the main store links could be generated using some other link based module that could be spidered and used to pass pagerank (PR) around the site effectively.

I am just trying to decide do I stick with DNN (my tried and true site tool) for a large eComm shop or just go with the others and try out YahooStores or one of the others. I know the DNN marketplace is based on DNN and ASPDotNetStoreFront, but for some reason, I don't really consider DNN Marketplace a big time eComm shop. I hope no one takes that the wrong way...because I am a huge DNN supporter, but just not sure about its applicability at the large eComm level. By large I am speaking of at least $50K per month in sales volume. Maybe DNN Marketplace already exceeds that. Could someone say what volume it does? Some of the SN gurus talk about YahooStores being scalable to about $50K per month, but then recommend moving to larger systems once the site moves beyond that level. Some SN members are doing $500K to $3M a month.

So I am asking for help and guidance.
