Note that in the case of vector TAB files, support is for reading and also writing of new layers.  Editing of an existing TAB is not currently possible.

Note that registration is not _via a TAB file_.  QGIS only supports TAB files that actually contain vector data, not the TAB files that MapInfo uses to refer to any non-TAB data (vector or raster).
Registration is either by creating a new file which contains the georeferencing information (this would need to be a geotiff or something which supports that), or via an ESRI style "world file" (these often have extensions like .wld .jgw .tfw etc).  I seem to remember that MapInfo is too useless to understand world files, but I could be wrong (maybe it was too useless to understand the built-in georeferencing in ecw files or something?).
Both world files and the georeferencing TAB files are plain text, so you can create one from the other if necessary.

I think there are _2_ web clients now :)
