@Gábor: I think they meant DAE format.
Yes, thank you for the correction.
I could imagine a server-side software pack what does convert the .skp at server-side to a webgl digestible format and creates the html for it. But it won't be a free solution for sure.
Exporting the file at client-side to a format what already has ready made webgl loader or using an include of an already existing web viewer is probably the most cost-effective for small firms. Though a little bit more labor intensive than a ready-made custom tailored server-side pack.
May I ask the original poster why is it so important to host it on their own server?
