I'm not sure what you mean. If I was asked to solve the problem of bookmarking pages created using POST, I would start by adjusting the bookmark editor and add a field for the POST data. After that it would simply be a case of ensuring it was filled in correctly and used correctly.
If I had written a browser myself, I would say this would amount to a morning's work but would expect to fit in elevenses.
In the afternoon, I might think about limiting the feature to certain sites i.e. a list of search engines, but make the list user-editable.
