I agree that this still is a problem: where can (organic) chemists host their data? TROS hints as Wikipedia, but an encyclopedia is not always the most suited place for cutting edge chemistry (article can easily be biased, contain (science) political views, etc...). I would suggest a blog would be a good start, and if proper markup would be used services like Chemical blogspace would automatically aggregate it.
However, something less volatile might be interesting. So, what we need is an overview of web databases where experimental chemistry data can be hosted. I'll start one, and annotate resources with license, on delicious.com, using the tags chemistry +web +database +open +submission, and regularly summarize things here.
In the below table, the last column indicated the most liberal license you can use to host your data:
|NMRShiftDB||NMR spectra||GNU FDL|
|ChemSpider||Structures, links to papers, spectra||open data|
There are some obvious gaps here, if you consider a typical experimental section. What to do with an measure melting point, IR spectra, mass spectral information, and measured elemental composition.
