All these four programs use a file with MDF markup (see below) to encode the dictionary information.
The order of the marker is not fully fixed in the MDF convention. LIFT (see below) is an XML format in which MDF formatted dictionaries may be encoded after some fixes. WeSay stores the lexical data in the LIFT format. WeSay includes an export function for MDF. This means that LexiquePro may be used to printout a dictionary.
A particular good combination for a new project is WeSay combined with LexiquePro.
Toolbox has been used in the last 12 years in the NUFU project to produce dictionaries.
File formats

Conclusion:
- all schemes are implementations of LMF
- Interchange results in loss of implied information
- Tools lack support for interchange
MDF
MDF = Multi-Dictionary Formatter MDF was originally a DOS program to printout dictionaries which had markers like \lx for the lexeme, \ge for the gloss English etc.
The way of encoding dictionary information persisted but the programs which do the printout have changed. These days LexiquePro offers good options for printing out a dictionary. You just choose 'File/Open' and point it to an MDF dictionary file. Then you are guided through a series of questions to load the dictionary. Menu 'File/Export' allows you to produce an MSWord or OpenOffice file with the printout.

The e-book http://www.sil.org/computing/shoebox/MDF_2000.pdf gives lexicographic principles and explains the markup. http://wiki.lingtransoft.info/tutorials/mdf gives a summary on the use of individual markers.
LIFT
LIFT (Lexicon Interchange FormaT) is an XML format for storing lexical information, as used in the creation of dictionaries. It's not necessarily the format for your lexicon. That can be tied to whatever program you're using. But LIFT allows you to move that data between programs (hence the term 'interchange').
LIFT is also a decent archiving option. Not because it will be around in 50 years, but because people will still be able to read it with any text editor and easily make use of it, even then. (You think that's true of your non-SOLID Standard Format file? We should have a chat.)
LIFT has been designed to have a long life but also to be relatively easy to convert to and from existing lexicon formats, particularly Multi-Dictionary Formatter (MDF) and FieldWorks Language Explorer. http://code.google.com/p/lift-standard/
