No, definitely not. I know manyfoot's internals. The extra smart macros
you need rather are table etc. macros than footnote macros.
(They may redefine \footnote such that the footnote text is stored in a hook
that eventually will execute \footnotetext's.)
Cf. the UK FAQ on footnotes in tables and in captions:

Here is workaround for the problem of more than one footnote
"in a prison":

\newcounter{save}
\newcommand{\transferto}[2]{\setcounter{#2}{\value{#1}}}
\newcommand{\stepfootnotetext}{\stepcounter{footnote}\footnotetext}

Alpha\footnote{alpha}
\transferto{footnote}{save}
\begin{tabular}{c}
A\footnotemark\\B\footnotemark
\end{tabular}
\transferto{save}{footnote}
\stepfootnotetext{a}
\stepfootnotetext{b}
Omega\footnote{omega}

I also have some private macros using labels to find the
correct footnote number. And it appears to me that I found
a much smarter package of this kind somewhere else.
But right now it comes to my mind that I rather should
generalize the hook thing -- but I must stop here.

HTH -- Uwe.
