I have no problem of aligning two or more \framedtext boxes bottomwise on the baseline, nor centering them vertically within a \vcenter.
But I do not succeed in placing them with their top aligned without the following trick: typeset them in a box, determine largestheight and then typeset again each within: \vbox to largestheight and \vill'ed to the bottom.

All very well, but it is disastrous when there are side effects: twice typesetting then fails in some instances.
I hope I described the question sufficiently clear, because an MWE is not so minimal.

Therefore my question: how can I align two or more \framedtext's thus:

|----------] |----------] |----------] ...
|          ] [          ] [          ]
|          ] [          ] [          ]
|          ] [          ] [          ]
|          ] |----------] [          ]
|          ]              [          ]
|          ]              [          ]
|----------]              [          ]
                          |----------]
