Well, the "Unmeasured Staff" command seemed to be in a bit of a state,
so I've upgraded it. 
The 256/1 time signature that Unmeasured Staff sets is what Denemo uses
as the time signature for its "bars" - basically meaning allow any
amount of notes in each Denemo "bar". But for typesetting purposes the
relevant thing is that it issues a "\cadenzaOn" to LilyPond. This turns
off LilyPond's automatic barlines and beaming. What was strange is that
it left it up to you to turn off the typesetting of the time signature
- see Score->Typesetter->(Print) Don't Engrave Time Signatures.
So the new version does all that for you.
You didn't actually say in any detail what you wanted to do - the above
allows you to place notes, bar lines, and beams freely in the typeset
score, but bar lines will act like "Marks" - that is they will be
placed in the same musical moment in all staffs. If you want to have
unequal bar lengths at the same moment in different staffs you have to
tell LilyPond to do that - see 
http://lilypond.org/doc/v2.18/Documentation/notation/displaying-rhythms#unmetered-music

"These predefined commands affect all staves in the score, even when
placed in just one Voice context. To change this, move the
Timing_translator from the Score context to the Staff context."

For the current version of Denemo, you can just use the 
Time Signatures->Start Cadenza 
command at the start of your staffs ...
