I'll have a more detailed look at it later (remind me that we need to 
formalize this \???? namespace for modules issue; we might need \??? for 
the core soon as we run out of \??'s).

I wonder what the side effects of \everyvbox are as the next box content 
can have vboxes itself (ok, you can do an everyvbox\emptytoks inside the 
\everyvbox); maybe \dowithnextboxcontent can be used here

\def\dodofancybreak
   {\begingroup
    \everyvbox
      {\setupalign[\fancybreakparameter\c!align]%
       \doifmode\s!mkiv{\dosetfancybreakattributes\c!style\c!color}}%
    \dowithnextbox
      {\blank[\fancybreakparameter\c!spacebefore]%
       \flushnextbox
       \blank[\fancybreakparameter\c!spaceafter]%
       \checknextindentation[\fancybreakparameter\c!indentnext]%
       \dorechecknextindentation
       \endgroup}
      \normalvbox}

so:

    \dowithnextboxcontent
      {\setupalign[\fancybreakparameter\c!align]%
       \doifmode\s!mkiv{\dosetfancybreakattributes\c!style\c!color}}%
      {\blank[\fancybreakparameter\c!spacebefore]%
       \flushnextbox

Another convention could be

\doifmode\s!mkiv{\let\dosetfancybreakattributes\gobbletwoarguments}

so that you then get (less testing):

    \dowithnextboxcontent
      {\setupalign[\fancybreakparameter\c!align]%
       \dosetfancybreakattributes\c!style\c!color}%
      {\blank[\fancybreakparameter\c!spacebefore]%
       \flushnextbox

As you write nice and clean modules that are perfect examples for 
others, we should take some time at the context conference and see if we 
can derive some 'module writing conventions'.

I wonder if I should finaly make a definer for \fancybreakparameter like 
cases. I had one once but it looked quite horrible and there are subtle 
differences between all cases but I'll give it a try some day soon.
